My understanding is that the overboost is only available on the 335is (N54) and not as part of the PPK. I have never seen anything that talks about the overboost with the PPK. Can you share how it is you have the overboost with the PPK

thanks

I have an SE version of the 335i that came out late last summer that has the same setup as the IS except for the DCT

If you HAD overboost (only available on the 335is or 1M), it's gone once you add the COBB tune. The stock tune is set for 8 psi, overboost takes it up to 12. Stage 1 N54 Maps run between 10-12 psi (Drive, Sport, Aggressive).

I have NO idea what the boost levels are for the N55, but with the COBB OTS Maps there are no "overboost" conditions. Just nice gradual boost curves that are appropriate to the mod level of the car.

Thanks for the response, again as above, I have the same setup as the 335is sans the DCT

If thats the case, then you have a N54 motor. My understanding is that only the IS still uses the N54 motor, so I doubt that you have the same thing as an IS without the DCT. More likely you have the N55 with a factory installed PPK and it does not have overboost. There is no factory overboost on the N55

Yeah.......... I think I would know what engine I have don't you?, its an N55, take a read....look about a third of the way down where it mentions overboost function

Dude, I have the same car, it most definitely HAS the overboost function, N55, these cars came out for a short period last summer, check the production weeks

We are looking to hunt down a customer with a 2011 manual transmission (MT) N55 to test with in the Austin area. If you or someone you know is in the Austin area or willing to travel here, please let us know. We are happy to get a 135i or 335i.

DFW customers may work as well.

Who's getting excited? I am!

Cheers,

Hi.
I have one with 20,000 miles on it. I live in Fulshear, TX, about 150 miles from Austin. My car is stock with no PPK. Are you still interested in a tester? Surprised that there is no one closer with a manual transmission.
